How can I avoid dehydration due to the incredibly dry air in planes?
Drink eight ounces of water every hour. Airplane air has only 1% to 10% humidity, even less than most deserts! You’ll need more than the two small cart drinks offered on most flights. Since you cannot bring your own bottled water, ask for water and juices from the stewardess onboard and avoid coffee, alcohol and carbonated drinks, which are dehydrating diuretics.
